Glennon, creator of the Momastery website and author of her memoir Love Warrior, had come out last November, saying on Facebook she was in a relationship with Abby.

"I'm going to share with you my new love," she wrote. "Her name is Abby. You might recognize her from soccer. She was one of the best players of all time, and she has been a fierce and committed advocate for women's equality for a decade. And honestly? Those are the least impressive things about her."
